Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone rubber, sealants are RTV (room-temperature vulcanizing).

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.

Designed to withstand extreme environments, these fluoroelastomer sealants have excellent resistance to sulfuric acid, hydrochloric acid, nitric acid, gasoline, and oil. Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

Elongation and joint expansion/compression tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation. For high-wear applications, choose a harder sealant for the most abrasion resistance.

These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. They’re non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Tested to meet ASTM E595, a standard used by NASA, these sealants fill joints and seams while releasing almost no volatile emissions that could damage sensitive electronics, even in a vacuum. Made of silicone rubber, they’re RTV (room-temperature vulcanizing), so they’ll fully harden at room temperature.

Elongation indicates flexibility—the higher the value is, the more a sealant can stretch.

Seal concrete joints in high-traffic areas—these sealants stand up to heavy wear and tear, such as steel wheel traffic. They're non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone rubber, sealants are RTV (room-temperature vulcanizing).

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Form seals that resist punctures, cuts, and abrasion to withstand heavy wear and tampering. These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

Seal concrete joints in high-traffic locations—these sealants stand up to heavy wear and tear, such as steel wheel traffic. Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Impervious to the swelling effects of oils, fuels, and solvents, use this high-strength silicone rubber sealant to assemble and repair fuel systems and tanks. Silicone rubber forms a tough, rubbery, UV-resistant seal that remains flexible over time. It's non-sagging, so it won't drip from vertical and overhead surfaces. Also known as RTV (room-temperature vulcanizing).

Elongation and joint expansion/compression tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. This sealant is best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

Keep out the elements by sealing roof joints. These sealants are non-sagging, so they won't drip from vertical and overhead surfaces. They are good for use in environments with wide temperature fluctuation.
